IMPROVEMENT IN MACHINES FOR MAKING HOLLOW CYLINDERS OF PAPER.

Specification forming part of Letters Patent No. 152,803, dated July 7,1874; application filed May 1, 1874.

To all whom it may concern:

Be it known that I, MARBLE D. KEENEY, of Rockton, in the county oflVinnebago and State of Illinois, have invented a new and ImprovedMachine for Making Hollow Cylinders of Paper, of which the following isa specification:

In the accompanying drawing, Figure 1 represents avertical transversesection of my improved machine for making cylindrical paper boxes; andFig. 2, a horizontal section of the same on the line 0 c, Fig. 1.

Similar letters of reference indicate correspondin g parts.

The object of my invention is to provide, for

the manuracture of cylindrical paper boxes orbarrels used in the packingof flour and simi lar substances, an improved machine or ap-'wedge-piece, so as to hold the edge of the continnous paper firmly inthe clamping-joint by spreading the other joint, and form then the boxor barrel on the roller.

In the drawing, A represents the forming roller, which is keyed to theouter free end of shaft a, turning in bearings of standards I), whichare placed at one side of roller A. The roller A is rotated by afriction-pulley and belt in connection with the drivingshaft. Boiler Ais constructed of two semicircular sections, B B, which are connected bydiametrical arms (I d, the arms (I of one section, B, being keyed toshaft (1, while the arms (1 of the other section are titted around theenlarged part of the shaft-embracing arms d. Both sections, B B, arehinged by lugs c of arms (1 and pivot-pins a, about midway between thejoint of the sections and the shaft, into corresponding recesses c ofarms d. A lever, O, is pivoted near the opposite joint of sections B Bto arm (1, passing parallel to shaft to, between the other arms d cl, tothe outside of the roller, and projecting with its central wedge part 0into inclined recesses f of the sections B B. On pressing the wedge 0against the inclined recesses f, the sections B B are spread apart,swinging on the pi votpins 0 and cause thereby the firm closing of theopposite joint. Guide-pins g of section B, near spreading-joint, serveto produce the uniform and steady motion of section B.

The operation of the apparatus is as follows The end of the strip orroll of continuous paper is inserted between the griping-joint of thesections B B, the other joint being then expanded to its full size bythe action of the wedge-lever thereon, so that the paper is firmly boundby the griping-joint. The forming-roller is then revolved and the gluesizing or paste evenly distributed by a suitable device-as, forinstance, by a pipe with small perforations, connected with thepaste-tank above the forming-roller. The paper is fed from the rolluntil the desired thickness is obtained, when the roller is stopped andthe ends of the paper fastened by means of claspbrads driven through theseveral layers on the edge of one ofthe semicircular sections, which iscovered with iron lining or band for clinching the brads. The paper isthen cut and the end thinned off to be held by the paste. The barrel orbox is then taken 01f from the roller by withdrawing the wedge'lever andcontract ing its size, which releases the end of the sheet from thegriping-joint of the sections, and allows the ready detaching of thebox. The paper box is then placed into the pressingcylinder, afterwarddried, provided with heads, and finished in suitable manner to beapplied for the purpose of packing flour of all kinds and similararticles.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The combination, with two roll-sections, B B, and twodiametrical arms or connections, (1 cl, the former hinged to a pin, a,passing through the lug c of one arm, and a recess, a, of the other, ofthe lever O, pivoted at one end, hav ing the other free, and having anintermediate wedge, 0, all as shown and described, for the purposespecified.
